DETAILED DESCRIPTION

Vasopressin and Peptides of the Invention.

Vasopressin, a peptide hormone, acts to regulate water retention in thebody and is a neurotransmitter that controls circadian rhythm,thermoregulation, and adrenocorticotrophic hormone (ACTH) release.Vasopressin is synthesized as a pro-hormone in neurosecretory cells ofthe hypothalamus, and is subsequently transported to the pituitary glandfor storage. Vasopressin is released upon detection of hyperosmolalityin the plasma, which can be due to dehydration of the body. Uponrelease, vasopressin increases the permeability of collecting ducts inthe kidney to reduce renal excretion of water. The decrease in renalexcretion of water leads to an increase in water retention of the bodyand an increase in blood volume. At higher concentrations, vasopressinraises blood pressure by inducing vasoconstriction.

Vasopressin acts through various receptors in the body including, forexample, the V1, V2, V3, and oxytocin-type (OTR) receptors. The V1receptors occur on vascular smooth muscle cells, and the major effect ofvasopressin action on the V1 receptor is the induction ofvasoconstriction via an increase of intracellular calcium. V2 receptorsoccur on the collecting ducts and the distal tubule of the kidney. V2receptors play a role in detection of plasma volume and osmolality. V3receptors occur in the pituitary gland and can cause ACTH release uponvasopressin binding. OTRs can be found on the myometrium and vascularsmooth muscle. Engagement of OTRs via vasopressin leads to an increaseof intracellular calcium and vasoconstriction.

Vasopressin is a nonapeptide, illustrated below (SEQ ID NO. 1):

At neutral to acidic pH, the two basic groups of vasopressin, theN-terminal cysteine, and the arginine at position eight, are protonated,and can each carry an acetate counterion. The amide groups of theN-terminal glycine, the glutamine at position four, and the asparagineat position five, are susceptible to modification when stored asclinical formulations, such as unit dosage forms. The glycine,glutamine, and asparagine residues can undergo deamidation to yield theparent carboxylic acid and several degradation products as detailed inEXAMPLE 1 and TABLE 1 below.

Deamidation is a peptide modification during which an amide group isremoved from an amino acid, and can be associated with proteindegradation, apoptosis, and other regulatory functions within the cell.Deamidation of asparagine and glutamine residues can occur in vitro andin vivo, and can lead to perturbation of the structure and function ofthe affected proteins. The susceptibility to deamidation can depend onprimary sequence of the protein, three-dimensional structure of theprotein, and solution properties including, for example, pH,temperature, ionic strength, and buffer ions. Deamidation can becatalyzed by acidic conditions. Under physiological conditions,deamidation of asparagine occurs via the formation of a five-memberedsuccinimide ring intermediate by a nucleophilic attack of the nitrogenatom in the following peptide bond on the carbonyl group of theasparagine side chain. Acetylation is a peptide modification whereby anacetyl group is introduced into an amino acid, such as on the N-terminusof the peptide.

Vasopressin can also form dimers in solution and in vivo. Thevasopressin dimers can occur through the formation of disulfide bridgesthat bind a pair of vasopressin monomers together. The dimers can formbetween two parallel or anti-parallel chains of vasopressin.

Vasopressin and associated degradation products or peptides are listedin TABLE 1 below. All amino acids are L-stereoisomers unless otherwisedenoted.

A formulation of vasopressin can be used to regulate plasma osmolalityand volume and conditions related to the same in a subject. Vasopressincan be used to modulate blood pressure in a subject, and can beindicated in a subject who is hypotensive despite treatment with fluidand catecholamines.

Vasopressin can be used in the treatment of, for example, vasodilatoryshock, post-cardiotomy shock, sepsis, septic shock, cranial diabetesinsipidus, polyuria, nocturia, polydypsia, bleeding disorders, VonWillebrand disease, haemophilia, platelet disorders, cardiac arrest,liver disease, liver failure, hypovolemia, hemorrhage, oesophagealvariceal haemorrhage, hypertension, pulmonary hypertension, renaldisease, polycystic kidney disease, blood loss, injury, hypotension,meniere disease, uterine myomas, brain injury, mood disorder.Formulations of vasopressin can be administered to a subject undergoing,for example, surgery or hysterectomy.

Plasma osmolality is a measure of the plasma's electrolyte-water balanceand relates to blood volume and hydration of a subject. Normal plasmaosmolality in a healthy human subject range from about 275milliosmoles/kg to about 295 milliosmoles/kg. High plasma osmolalitylevels can be due to, for example, diabetes insipidus, hyperglycemia,uremia, hypernatremia, stroke, and dehydration. Low plasma osmolalitycan be due to, for example, vasopressin oversecretion, improperfunctioning of the adrenal gland, lung cancer, hyponatremia,hypothyroidism, and over-consumption of water or other fluids.

Septic shock can develop due to an extensive immune response followinginfection and can result in low blood pressure. Causes of sepsis caninclude, for example, gastrointestinal infections, pneumonia,bronchitis, lower respiratory tract infections, kidney infection,urinary tract infections, reproductive system infections, fungalinfections, and viral infections. Risk factors for sepsis include, forexample, age, prior illness, major surgery, long-term hospitalization,diabetes, intravenous drug use, cancer, use of steroidal medications,and long-term use of antibiotics. The symptoms of sepsis can include,for example, cool arms and legs, pale arms and legs, extreme bodytemperatures, chills, light-headedness, decreased urination, rapidbreathing, edema, confusion, elevated heart rate, high blood sugar,metabolic acidosis, respiratory alkalosis, and low blood pressure.

Vasopressin can also be administered to regulate blood pressure in asubject. Blood pressure is the measure of force of blood pushing againstblood vessel walls. Blood pressure is regulated by the nervous andendocrine systems and can be used as an indicator of a subject's health.Chronic high blood pressure is referred to as hypertension, and chroniclow blood pressure is referred to as hypotension. Both hypertension andhypotension can be harmful if left untreated.

Blood pressure can vary from minute to minute and can follow thecircadian rhythm with a predictable pattern over a 24-hour period. Bloodpressure is recorded as a ratio of two numbers: systolic pressure (mmHg), the numerator, is the pressure in the arteries when the heartcontracts, and diastolic pressure (mm Hg), the denominator, is thepressure in the arteries between contractions of the heart. Bloodpressure can be affected by, for example, age, weight, height, sex,exercise, emotional state, sleep, digestion, time of day, smoking,alcohol consumption, salt consumption, stress, genetics, use of oralcontraceptives, and kidney disease.

Blood pressure for a healthy human adult between the ages of 18-65 canrange from about 90/60 to about 120/80. Hypertension can be a bloodpressure reading above about 120/80 and can be classified ashypertensive crisis when there is a spike in blood pressure and bloodpressure readings reach about 180/110 or higher. Hypertensive crisis canbe precipitated by, for example, stroke, myocardial infarction, heartfailure, kidney failure, aortic rupture, drug-drug interactions, andeclampsia. Symptoms of hypertensive crisis can include, for example,shortness of breath, angina, back pain, numbness, weakness, dizziness,confusion, change in vision, nausea, and difficulty speaking.

Vasodilatory shock can be characterized by low arterial blood pressuredue to decreased systemic vascular resistance. Vasodilatory shock canlead to dangerously low blood pressure levels and can be corrected viaadministration of catecholamines or vasopressin formulations.Vasodilatory shock can be caused by, for example, sepsis, nitrogenintoxication, carbon monoxide intoxication, hemorrhagic shock,hypovolemia, heart failure, cyanide poisoning, metformin intoxication,and mitochondrial disease.

Post-cardiotomy shock can occur as a complication of cardiac surgery andcan be characterized by, for example, inability to wean fromcardiopulmonary bypass, poor hemodynamics in the operating room,development of poor hemodynamics post-surgery, and hypotension.

Non-limiting examples of methods that can be used to identify peptidesof the invention include high-performance liquid chromatography (HPLC),mass spectrometry (MS), Matrix Assisted Laser Desorption IonizationTime-of-Flight (MALDI-TOF), electrospray ionization Time-of-flight(ESI-TOF), gas chromatography-mass spectrometry (GC-MS), liquidchromatography-mass spectrometry (LC-MS), and two-dimensional gelelectrophoresis.

HPLC can be used to identify peptides using high pressure to separatecomponents of a mixture through a packed column of solid adsorbentmaterial, denoted the stationary phase. The sample components caninteract differently with the column based upon the pressure applied tothe column, material used in stationary phase, size of particles used inthe stationary phase, the composition of the solvent used in the column,and the temperature of the column. The interaction between the samplecomponents and the stationary phase can affect the time required for acomponent of the sample to move through the column. The time requiredfor component to travel through the column from injection point toelution is known as the retention time.

Upon elution from the column, the eluted component can be detected usinga UV detector attached to the column. The wavelength of light at whichthe component is detected, in combination with the component's retentiontime, can be used to identify the component. Further, the peak displayedby the detector can be used to determine the quantity of the componentpresent in the initial sample. Wavelengths of light that can be used todetect sample components include, for example, about 200 nM, about 225nm, about 250 nm, about 275 nm, about 300 nm, about 325 nm, about 350nm, about 375 nm, and about 400 nm.

Mass spectrometry (MS) can also be used to identify peptides of theinvention. To prepare samples for MS analysis, the samples, containingthe proteins of interest, are digested by proteolytic enzymes intosmaller peptides. The enzymes used for cleavage can be, for example,trypsin, chymotrypsin, glutamyl endopeptidase, Lys-C, and pepsin. Thesamples can be injected into a mass spectrometer. Upon injection, all ormost of the peptides can be ionized and detected as ions on a spectrumaccording to the mass to charge ratio created upon ionization. The massto charge ratio can then be used to determine the amino acid residuespresent in the sample.

EXAMPLES Example 1 Impurities of Vasopressin as Detected by HPLC

To analyze degradation products of vasopressin that can be present in anillustrative formulation of vasopressin, gradient HPLC was performed toseparate vasopressin from related peptides and formulation components.TABLE 2 below depicts the results of the experiment detailing thechemical formula, relative retention time (RRT), molar mass, andstructure of vasopressin and detected impurities.

Vasopressin was detected in the eluent using UV absorbance. Theconcentration of vasopressin in the sample was determined by theexternal standard method, where the peak area of vasopressin in sampleinjections was compared to the peak area of vasopressin referencestandards in a solution of known concentration. The concentrations ofrelated peptide impurities in the sample were also determined using theexternal standard method, using the vasopressin reference standard peakarea and a unit relative response factor. An impurities marker solutionwas used to determine the relative retention times of identified relatedpeptides at the time of analysis.

Experimental conditions are summarized in TABLE 2 below.

TABLE 2 Column YMC-Pack ODS-AM, 3 μm, 120 Å pore, 4.6 × 100 mm ColumnTemperature 25° C. Flow Rate 1.0 mL/min Detector 215 nm Note: ForIdentification a Diode Array Detector (DAD) was used with the range of200-400 nm.

The diluent used for the present experiment was 0.25% v/v Acetic Acid,which was prepared by transferring 2.5 mL of glacial acetic acid into a1-L volumetric flask containing 500 mL of water. The solution wasdiluted to the desired volume with water.

Phosphate buffer at pH 3.0 was used for mobile phase A. The buffer wasprepared by weighing approximately 15.6 g of sodium phosphate monobasicmonohydrate into a beaker. 1000 mL of water was added, and mixed well.The pH was adjusted to 3.0 with phosphoric acid. The buffer was filteredthrough a 0.45 μm membrane filter under vacuum, and the volume wasadjusted as necessary.

An acetonitrile:water (50:50) solution was used for mobile phase B. Toprepare mobile phase B, 500 mL of acetonitrile was mixed with 500 mL ofwater.

The working standard solution contained approximately 20 units/mL ofvasopressin. The standard solution was prepared by quantitativelytransferring the entire contents of 1 vial of USP Vasopressin RS withdiluent to a 50-mL volumetric flask.

The intermediate standard solution was prepared by pipetting 0.5 mL ofthe working standard solution into a 50-mL volumetric flask.

The sensitivity solution was prepared by pipetting 5.0 mL of theintermediate standard solution into a 50-mL volumetric flask. Thesolution was diluted to the volume with Diluent and mixed well.

A second working standard solution was prepared as directed under thestandard preparation.

A portion of the vasopressin control sample was transferred to an HPLCvial and injected. The control was stable for 120 hours when stored inautosampler vials at ambient laboratory conditions.

To prepare the impurities marker solution, a 0.05% v/v acetic acidsolution was prepared by pipetting 200.0 mL of a 0.25% v/v acetic acidsolution into a 1-L volumetric flask. The solution was diluted to thedesired volume with water and mixed well.

To prepare the vasopressin impurity stock solutions, the a solution ofeach impurity was prepared in a 25 mL volumetric flask and diluted with0.05% v/v acetic acid to a concentration suitable for HPLC injection.

To prepare the MAA/H-IBA (Methacrylic Acid/α-Hydroxy-isobutyric acid)stock solution, a stock solution containing approximately 0.3 mg/mLH-IBA and 0.01 mg/mL in 0.05% v/v acetic acid was made in a 50 mLvolumetric flask.

To prepare the chlorobutanol diluent, about one gram of hydrouschlorobutanol was added to 500 mL of water. Subsequently, 0.25 mL ofacetic acid was added and the solution was stirred to dissolve thechlorobutanol.

To prepare the impurity marker solution, vasopressin powder was mixedwith the impurity stock solutions prepared above.

The solutions were diluted to volume with the chlorobutanol diluent. Thesolutions were aliquoted into individual crimp top vials and stored at2-8° C. At time of use, the solutions were removed from refrigeration(2-8° C.) and allowed to reach room temperature.

The vasopressin impurity marker solution was stable for at least 120hours when stored in auto-sampler vials at ambient laboratoryconditions. The solution was suitable for use as long as thechromatographic peaks could be identified based on comparison to thereference chromatogram.

To begin the analysis, the HPLC system was allowed to equilibrate for atleast 30 minutes using mobile phase B, followed by time 0 min gradientconditions until a stable baseline was achieved.

The diluent was injected at the beginning of the run, and had no peaksthat interfered with Vasopressin at around 18 minutes as shown in FIG.1.

A single injection of the sensitivity solution was performed, whereinthe signal-to-noise ratio of the Vasopressin was greater than or equalto ten as shown in FIG. 2.

A single injection of the impurities marker solution was then made. Thelabeled impurities in the reference chromatogram were identified in thechromatogram of the marker solution based on their elution order andapproximate retention times shown in FIG. 3 and FIG. 4. FIG. 4 is azoomed in chromatograph of FIG. 3 showing the peaks that eluted between15 and 30 minutes. The nomenclature, structure, and approximateretention times for individual identified impurities are detailed inTABLE 3.

A single injection of the working standard solution was made to ensurethat the tailing factor of the vasopressin peak was less than or equalto about 2.0 as shown in FIG. 5.

A total of five replicate injections of the working standard solutionwere made to ensure that the relative standard deviation (% RSD) of thefive replicate vasopressin peak areas was not more than 2.0%.

Two replicate injections of the check standard preparation were toconfirm that the check standard conformity was 99.0%-101.0%. Oneinjection of the control sample was made to confirm that the assay ofthe control sample met the control limits established for the sample.

Then, one injection of the working standard solution was made.

Following the steps above done to confirm system suitability, a singleinjection of each sample preparation was made. The chromatograms wereanalyzed to determine the vasopressin and impurity peak areas. Thechromatogram is depicted in FIG. 6.

The working standard solution was injected after 1 to 4 sampleinjections, and the bracketing standard peak areas were averaged for usein the calculations to determine peak areas of vasopressin andassociated impurities.

The relative standard deviation (% RSD) of vasopressin peak areas forthe six injections of working standard solution was calculated byincluding the initial five injections from the system suitability stepsabove and each of the subsequent interspersed working standard solutioninjections. The calculations were done to ensure that each of the % RSDwere not more than 2.0%.

The retention time of the major peak in the chromatogram of the samplepreparation corresponded to that of the vasopressin peak in the workingstandard solution injection that preceded the sample preparationinjection.

The UV spectrum (200-400 nm) of the main peak in the chromatogram of thesample preparation compared to the UV spectrum of vasopressin in theworking standard preparation. FIG. 7 depicts a UV spectrum of avasopressin sample and FIG. 8 depicts a UV spectrum of vasopressinstandard.

To calculate the vasopressin units/mL, the following formula was used:

${{Vasopressin}\mspace{14mu}{units}\text{/}{mL}} = {\frac{R_{U}}{R_{S}} \times {Conc}\mspace{14mu}{STD}}$

where:

-   -   R_(U)=Vasopressin peak area response of Sample preparation.    -   R_(S)=average vasopressin peak area response of bracketing        standards.    -   Conc STD=concentration of the vasopressin standard in units/mL

To identify the impurities, the % Impurity and identity for identifiedimpurities (TABLE 3) that are were greater than or equal to 0.10% werereported. Impurities were truncated to 3 decimal places and then roundedto 2 decimal places, unless otherwise specified.

The impurities were calculated using the formula below:

${\%\mspace{14mu}{impurity}} = {\frac{R_{I}}{R_{S}} \times \frac{{Conc}\mspace{14mu}{STD}}{20\mspace{14mu} U\text{/}{mL}} \times 100\%}$

where:

-   -   R_(I)=Peak area response for the impurity    -   20 U/mL=Label content of vasopressin

Example 2 Investigation of pH

To determine a possible pH for a vasopressin formulation with good shelflife, vasopressin formulations were prepared in 10 mM citrate bufferdiluted in isotonic saline across a range of pH. Stability was assessedvia HPLC as in EXAMPLE 1 after incubation of the formulations at 60° C.for one week. FIG. 9 illustrates the results of the experiment. Thegreatest level of stability was observed at pH 3.5. At pH 3.5, thepercent label claim (% LC) of vasopressin was highest, and theproportion of total impurities was lowest.

Example 3 Effect of Peptide Stabilizers on Vasopressin Formulation

To observe the effect of stabilizers on the degradation of vasopressin,a series of peptide stabilizers were added to a vasopressin formulationas detailed in TABLE 4. Stability of vasopressin was assessed via HPLCafter incubation of the formulations at 60° C. for one week.

TABLE 4 PEG Poloxamer n-Methylpyrrolidone Ethanol 400 Glycerol 188HPbCD^(a) (NMP)  1%  1%  1%  1%  1%  1% 10% 10% 10% 10% 10% 10%^(a)Hydroxypropyl beta-Cyclodextrin

FIG. 10 illustrates the stability of vasopressin in terms of % labelclaim at varying concentrations of stabilizer. The results indicate thatthe tested stabilizers provided a greater stabilizing effect at 1%concentration than at 10%. Also, in several cases the stabilizationeffect was about 5% to about 10% greater than that observed in theexperiments of EXAMPLE 2.

Example 4 Effect of Buffer and Divalent Metals on VasopressinFormulation

To determine whether different combinations of buffers and use ofdivalent metals affect vasopressin stability, vasopressin formulationswith varying concentrations of citrate and acetate buffers and variableconcentrations of calcium, magnesium, and zinc ions were prepared.Solutions of 0 mM, 10 mM, 20 mM, and 80 mM calcium, magnesium, and zincwere prepared and each was combined with 1 mM or 10 mM of citrate oracetate buffers to test vasopressin stability.

The tested combinations provided vasopressin stability comparable tothat of a vasopressin formulation lacking buffers and divalent metals.However, that the addition of divalent metal ions was able to counteractthe degradation of vasopressin caused by the use of a citrate buffer.

Example 5 Illustrative Formulations for Assessment of VasopressinStability

Example 6 Illustrative Vasopressin Formulation for Clinical Use

A formulation for vasopressin that can be used in the clinic is detailedin TABLE 5 below:

TABLE 5 Ingredient Function Amount (per mL) Vasopressin, USP ActiveIngredient 20 Units (~0.04 mg) Chlorobutanol, Hydrous NF Preservative5.0 mg Acetic Acid, NF pH Adjustment To pH 3.4-3.6 (~0.22 mg) Water forinjection, USP/EP Diluent QS

Example 7 Illustrative Regimen for Therapeutic Use of a VasopressinFormulation

Vasopressin is indicated to increase blood pressure in adults withvasodilatory shock (for example, adults who are post-cardiotomy orseptic) who remain hypotensive despite fluids and catecholamines.

Preparation and Use of Vasopressin.

Vasopressin is supplied in a carton of 25 multi-dose vials eachcontaining 1 mL vasopressin at 20 units/mL.

Vasopressin is stored between 15° C. and 25° C. (59° F. and 77° F.), andis not frozen. Alternatively, a unit dosage form of vasopressin can bestored between 2° C. and 8° C. for about 1 week, 2 weeks, 3 weeks, 4weeks, 5 weeks, 6 weeks, 7 weeks, or 8 weeks.

Vials of vasopressin are to be discarded 48 hours after first puncture.

Vasopressin is prepared according to TABLE 6 below:

TABLE 6 Mix Fluid Restriction? Final Concentration Vasopressin DiluentNo 0.1 units/mL 2.5 mL (50 units) 500 mL Yes 1 unit/mL 5 mL (100 units)100 mL

Vasopressin is diluted in normal saline (0.9% sodium chloride) or 5%dextrose in water (D5W) prior to use to either 0.1 units/mL or 1 unit/mLfor intravenous administration. Unused diluted solution is discardedafter 18 hours at room temperature or after 24 hours underrefrigeration.

Diluted vasopressin should be inspected for particulate matter anddiscoloration prior to use whenever solution and container permit.

The goal of treatment with vasopressin is optimization of perfusion tocritical organs, but aggressive treatment can compromise perfusion oforgans, like the gastrointestinal tract, for which function is difficultto monitor. Titration of vasopressin to the lowest dose compatible witha clinically-acceptable response is recommended.

For post-cardiotomy shock, a dose of 0.03 units/minute is used as astarting point. For septic shock, a dose of 0.01 units/minute isrecommended. If the target blood pressure response is not achieved,titrate up by 0.005 units/minute at 10- to 15-minute intervals. Themaximum dose for post-cardiotomy shock is 0.1 units/minute and forseptic shock 0.07 units/minute. After target blood pressure has beenmaintained for 8 hours without the use of catecholamines, tapervasopressin by 0.005 units/minute every hour as tolerated to maintaintarget blood pressure.

Vasopressin is provided at 20 units per mL of diluent, which is packagedas 1 mL of vasopressin per vial, and is diluted prior to administration.

Contraindications, Adverse Reactions, and Drug-Drug Interactions.

Vasopressin is contraindicated in patients with known allergy orhypersensitivity to 8-L-arginine vasopressin or chlorobutanol.Additionally, use of vasopressin in patients with impaired cardiacresponse can worsen cardiac output.

Adverse reactions have been observed with the use of vasopressin, whichadverse reactions include bleeding/lymphatic system disorders,specifically, hemorrhagic shock, decreased platelets, intractablebleeding; cardiac disorders, specifically, right heart failure, atrialfibrillation, bradycardia, myocardial ischemia; gastrointestinaldisorders, specifically, mesenteric ischemia; hepatobiliary disorders,specifically, increased bilirubin levels; renal/urinary disorders,specifically, acute renal insufficiency; vascular disorders,specifically, distal limb ischemia; metabolic disorders, specifically,hyponatremia; and skin disorders, specifically, and ischemic lesions.

These reactions are reported voluntarily from a population of uncertainsize. Thus, reliable estimation of frequency or establishment of acausal relationship to drug exposure is unlikely.

Vasopressin has been observed to interact with other drugs. For example,use of vasopressin with catecholamines is expected to result in anadditive effect on mean arterial blood pressure and other hemodynamicparameters. Use of vasopressin with indomethacin can prolong the effectof vasopressin on cardiac index and systemic vascular resistance.Indomethacin more than doubles the time to offset for vasopressin'seffect on peripheral vascular resistance and cardiac output in healthysubjects.

Further, use of vasopressin with ganglionic blocking agents can increasethe effect of vasopressin on mean arterial blood pressure. Theganglionic blocking agent tetra-ethylammonium increases the pressoreffect of vasopressin by 20% in healthy subjects.

Use of vasopressin with furosemide increases the effect of vasopressinon osmolar clearance and urine flow. Furosemide increases osmolarclearance 4-fold and urine flow 9-fold when co-administered withexogenous vasopressin in healthy subjects.

Use of vasopressin with drugs suspected of causing SIADH (Syndrome ofinappropriate antidiuretic hormone secretion), for example, SSRIs,tricyclic antidepressants, haloperidol, chlorpropamide, enalapril,methyldopa, pentamidine, vincristine, cyclophosphamide, ifosfamide, andfelbamate can increase the pressor effect in addition to theantidiuretic effect of vasopressin. Additionally, use of vasopressinwith drugs suspected of causing diabetes insipidus for example,demeclocycline, lithium, foscarnet, and clozapine can decrease thepressor effect in addition to the antidiuretic effect of vasopressin.

Halothane, morphine, fentanyl, alfentanyl and sufentanyl do not impactexposure to endogenous vasopressin.

Use of Vasopressin in Specific Populations.

Vasopressin is a Category C drug for pregnancy.

Due to a spillover into the blood of placental vasopressinase, theclearance of exogenous and endogenous vasopressin increases graduallyover the course of a pregnancy. During the first trimester of pregnancythe clearance is only slightly increased. However, by the thirdtrimester the clearance of vasopressin is increased about 4-fold and atterm up to 5-fold. Due to the increased clearance of vasopressin in thesecond and third trimester, the dose of vasopressin can be up-titratedto doses exceeding 0.1 units/minute in post-cardiotomy shock and 0.07units/minute in septic shock. Vasopressin can produce tonic uterinecontractions that could threaten the continuation of pregnancy. Afterdelivery, the clearance of vasopressin returns to preconception levels.

Overdosage.

Overdosage with vasopressin can be expected to manifest as a consequenceof vasoconstriction of various vascular beds, for example, theperipheral, mesenteric, and coronary vascular beds, and as hyponatremia.In addition, overdosage of vasopressin can lead less commonly toventricular tachyarrhythmias, including Torsade de Pointes,rhabdomyolysis, and non-specific gastrointestinal symptoms. Directeffects of vasopressin overdose can resolve within minutes of withdrawalof treatment.

Pharmacology of Vasopressin.

Vasopressin is a polypeptide hormone that causes contraction of vascularand other smooth muscles and antidiuresis, which can be formulated as asterile, aqueous solution of synthetic arginine vasopressin forintravenous administration. The 1 mL solution contains vasopressin 20units/mL, chlorobutanol, NF 0.5% as a preservative, and water forinjection, USP adjusted with acetic acid to pH 3.4-3.6.

The chemical name of vasopressin is Cyclo (1-6)L-Cysteinyl-L-Tyrosyl-L-Phenylalanyl-L-Glutaminyl-L-Asparaginyl-L-Cysteinyl-L-Prolyl-L-Arginyl-L-Glycinamide.Vasopressin is a white to off-white amorphous powder, freely soluble inwater. The structural formula of vasopressin is:

Molecular Formula: C₄₆H₆₅N₁₅O₁₂S₂; Molecular Weight: 1084.23

One mg of vasopressin is equivalent to 530 units. Alternatively, one mgof vasopressin is equivalent to 470 units.

The vasoconstrictive effects of vasopressin are mediated by vascular V1receptors. Vascular V1 receptors are directly coupled to phopholipase C,resulting in release of calcium, leading to vasoconstriction. Inaddition, vasopressin stimulates antidiuresis via stimulation of V2receptors which are coupled to adenyl cyclase.

At therapeutic doses, exogenous vasopressin elicits a vasoconstrictiveeffect in most vascular beds including the splanchnic, renal, andcutaneous circulation. In addition, vasopressin at pressor dosestriggers contractions of smooth muscles in the gastrointestinal tractmediated by muscular V1-receptors and release of prolactin and ACTH viaV3 receptors. At lower concentrations typical for the antidiuretichormone, vasopressin inhibits water diuresis via renal V2 receptors. Inpatients with vasodilatory shock, vasopressin in therapeutic dosesincreases systemic vascular resistance and mean arterial blood pressureand reduces the dose requirements for norepinephrine.

Vasopressin tends to decrease heart rate and cardiac output. The pressoreffect is proportional to the infusion rate of exogenous vasopressin.Onset of the pressor effect of vasopressin is rapid, and the peak effectoccurs within 15 minutes. After stopping the infusion, the pressoreffect fades within 20 minutes. There is no evidence for tachyphylaxisor tolerance to the pressor effect of vasopressin in patients.

At infusion rates used in vasodilatory shock (0.01-0.1 units/minute),the clearance of vasopressin is 9 to 25 mL/min/kg in patients withvasodilatory shock. The apparent half-life of vasopressin at theselevels is ≤10 minutes. Vasopressin is predominantly metabolized and onlyabout 6% of the dose is excreted unchanged in urine. Animal experimentssuggest that the metabolism of vasopressin is primarily by liver andkidney. Serine protease, carboxipeptidase and disulfide oxido-reductasecleave vasopressin at sites relevant for the pharmacological activity ofthe hormone. Thus, the generated metabolites are not expected to retainimportant pharmacological activity.

Carcinogenesis, Mutagenesis, Impairment of Fertility.

Vasopressin was found to be negative in the in vitro bacterialmutagenicity (Ames) test and the in vitro Chinese hamster ovary (CHO)cell chromosome aberration test. In mice, vasopressin can have an effecton function and fertilizing ability of spermatozoa.

Clinical Studies.

Increases in systolic and mean blood pressure following administrationof vasopressin were observed in seven studies in septic shock and eightstudies in post-cardiotomy vasodilatory shock.

Example 8 Effect of Temperature on Vasopressin Formulations

To test the effect of temperature on the stability of vasopressinformulation, solutions containing 20 units/mL vasopressin andchlorobutanol, adjusted to pH 3.5 with acetic acid, were prepared. OnemL of each vasopressin formulations was then filled into 3 cc vials.Each Vasopressin Formulation was stored either inverted or upright forat least three months, up to 24 months, at: (i) 5° C.; (ii) 25° C. and60% relative humidity; or (iii) 40° C. and 75% humidity, and the amountof vasopressin (U/mL) and % total impurities were measured periodically.TABLES 7-12 below display the results of the experiments at 5° C. Theresults of the experiments at 25° C. are included in TABLES 13-18. Allof the experiments were performed in triplicate. The results of theexperiments at 40° C. are included in TABLES 19-24. For each temperaturetested, three lots of the vasopressin formulation were stored for 24months (5° C. and 25° C.) and 3 months (40° C.), and measurements weretaken at regular intervals during the testing periods. “NMT” as used inthe tables denotes “not more than.”

The results of the above experiments suggested that storage in either anupright or inverted position did not markedly affect the stability ofvasopressin. The samples held at 5° C. exhibited little fluctuation invasopressin amounts over 24 months, and the amount of total impuritiesdid not increase above 3% during the testing period (TABLES 7-12). Thesamples held at 25° C. and 60% relative humidity exhibited a decrease invasopressin amount of about 10-12% after 24 months (TABLES 13-18). Theamount of impurities observed in the samples stored at 25° C. and 60%relative humidity after 24 months exceeded 13% in some samples, whereasthe amount of impurities observed in the samples stored at 5° C. did notexceed 3% after 24 months. After about three months, the samples held at40° C. exhibited a decrease in the amount of vasopressin of about10-12%. The amount of impurities observed at 40° C. exceeded 10% afterthree months, whereas the amount of impurities observed in the samplesstored at 5° C. was less than 3% after three months (TABLES 19-24).

Experiments were also conducted on the same samples above over thecourse of the experiments to measure the amount of individual impuritiesin the samples, pH of the samples, chlorobutanol content, particulatematter, antimicrobial effectiveness, and bacterial endotoxin levels(TABLES 25-42). (NR=no reading; ND=not determined; UI=unidentifiedimpurity).

The anti-microbial effectiveness of the solution was established todetermine the amount of antimicrobial agents in the formulation thatprotect against bacterial contamination. The bullets in the tables belowindicate that the sample was not tested for anti-microbial effectivenessat that specific time point.

The bacterial endotoxin levels were also measured for some of theformulations. The bullets in the tables below indicate that the samplewas not tested for bacterial endotoxin levels at that specific timepoint.

Example 9 Effect of pH 3.5-4.5 on Vasopressin Formulations

To test of effect of pH on vasopressin formulations, solutionscontaining 20 units/mL vasopressin, adjusted to pH 3.5, 3.6, 3.7, 3.8,3.9, 4, 4.1, 4.2, 4.3, 4.4, or 4.5 with 10 mM acetate buffer, wereprepared. One mL of each of the vasopressin formulations was then filledinto 10 cc vials.

The vasopressin formulations were stored for four weeks at: (i) 25° C.;or (ii) 40° C., and the assay (% label claim; vasopressin remaining) and% total impurities after four weeks were measured using the methodsdescribed in EXAMPLE 1. FIGS. 11 and 12 below display the results of theexperiments at 25° C. The results of the experiments at 40° C. areincluded in FIGS. 13 and 14.

The results of the experiments suggested that the stability of avasopressin formulation was affected by pH. At 25° C., the remainingvasopressin after four weeks was highest between pH 3.6 and pH 3.8 (FIG.11). Within the range of pH 3.6 to pH 3.8, the level of impurities waslowest at pH 3.8 (FIG. 12). At 25° C., pH 3.7 provided the higheststability for vasopressin (FIG. 11).

At 40° C., the remaining vasopressin after four weeks was highestbetween pH 3.6 and pH 3.8 (FIG. 13). Within the range of pH 3.6 to pH3.8, the level of impurities was lowest at pH 3.8 (FIG. 14). At 40° C.,pH 3.6 provided the highest stability for vasopressin (FIG. 13),

To test of effect of pH on vasopressin formulations, solutionscontaining 20 units/mL vasopressin, adjusted to pH 2.5, 2.6, 2.7, 2.8,2.9, 3, 3.1, 3.2, 3.3, or 3.4 with 10 mM acetate buffer were alsoprepared. One mL of each of the vasopressin formulations was then filledinto 10 cc vials.

The amount of vasopressin, impurities, and associated integration valueswere determined using the methods describes in EXAMPLE 1. The resultsfrom the stability tests on the vasopressin formulations from pH 2.5 to3.4 were plotted against the results from the stability tests onvasopressin formulations from pH 3.5 to 4.5 as disclosed in EXAMPLE 9,and are displayed in FIGS. 15-18.

The % total impurities for the pH 2.5 to 3.4 formulations and the pH 3.5to 4.5 formulations observed in the experiments conducted at 25° C. and40° C. are shown in FIGS. 15 (25° C.) and 16 (40° C.).

The vasopressin assay amount for the vasopressin pH 2.5 to 3.4formulations and the vasopressin pH 3.5 to 4.5 formulations observed inthe experiments conducted at 25° C. and 40° C. are shown in FIGS. 17(25° C.) and 18 (40° C.). The vasopressin assay is presented as a %assay decrease of vasopressin over the four-week study period, ratherthan absolute assay, because the amount of starting vasopressin variedbetween the vasopressin pH 2.5 to 3.4 formulations and the vasopressinpH 3.5 to 4.5 formulations.

The results of the above experiments suggested that the stability of avasopressin formulation was affected by pH. At 25° C., the percentdecrease in vasopressin after four weeks was lowest between pH 3.7 andpH 3.8 (FIG. 17). Within the range of pH 3.7 to pH 3.8, the level ofimpurities was lowest at pH 3.8 (FIG. 15). At 40° C., the percentdecrease in vasopressin after four weeks was lowest between pH 3.6 andpH 3.8 (FIG. 18). Within the range of pH 3.6 to pH 3.8, the level ofimpurities was lowest at pH 3.8 (FIG. 16).

Example 11 Intra-assay and Inter-analysis Precision of Vasopressin pHExperiments

The methods used to determine the % assay decrease and amount ofimpurities in the vasopressin solutions over time in EXAMPLE 10 had bothintra-assay and inter-analyst precision.

Intra-assay precision was demonstrated by performing single injectionsof aliquots of a vasopressin formulation (n=6; Chemist 1) from a commonlot of drug product and determining the assay and repeatability (% RSD;relative standard deviation). Inter-analyst precision was demonstratedby two different chemists testing the same lot of drug product; however,the chemists used different instruments, reagents, standardpreparations, columns, and worked in different laboratories. Theprocedure included a common pooling of 20 vials of vasopressin, whichwere assayed by the two chemists using different HPLC systems anddifferent HPLC columns. The vasopressin assay results (units/mL) andrepeatability (% RSD for n=6) were recorded and are reported in theTABLE 44 below.

TABLE 44 Precision of Vasopressin Results. Chemist 1 Chemist 2 Sample(units/mL) (units/mL) 1 19.74 19.65 2 19.76 19.66 3 19.77 19.66 4 19.7519.72 5 19.97 19.73 6 19.65 19.73 Mean 19.8 19.7 % RSD (≤2.0%) 0.5% 0.2%% Difference = 0.5% (acceptance criteria: ≤3.0%)${\%\mspace{14mu}{Difference}} = {\frac{\left( {{{Chemist}\mspace{14mu} 1_{Mean}} - {{Chemist}\mspace{14mu} 2_{Mean}}} \right)}{\left( {{{Chemist}\mspace{14mu} 1_{Mean}} + {{Chemist}\mspace{14mu} 2_{Mean}}} \right)} \times 200}$

The intra-assay repeatability met the acceptance criteria (% RSD≤2.0%)with values of 0.5% and 0.2%. The inter-analyst repeatability also metthe acceptance criteria (% difference≤3.0%) with a difference of 0.5%.

Example 12 Effect of Citrate Versus Acetate Buffer on VasopressinFormulations

To test the effect of citrate and acetate buffer on vasopressinformulations, a total of twelve solutions of 20 Units/mL vasopressinwere prepared in 1 mM citrate buffer, 10 mM citrate buffer, 1 mM acetatebuffer, and 10 mM acetate buffer. All of the solutions were prepared intriplicate. Each solution was adjusted to pH 3.5 with hydrochloric acid.

The vasopressin formulations were stored at 60° C. for 7 days, and theassay (% label claim; vasopressin remaining) and % total impuritiesafter 7 days were analyzed by HPLC using the procedure and experimentalconditions described in EXAMPLE 1.

The assay (% label claim; vasopressin remaining) and % total impuritiesfor each of the Vasopressin Buffered Formulations are reported in theTABLES 45 and 46 below.

TABLE 45 Assay (% label claim; vasopressin remaining) in the vasopressinformulations after storage at 60° C. for 7 days. Sample Buffer 1 2 3Average  1 mM citrate buffer 89.5% 89.7% 90.6% 89.9% 10 mM citratebuffer 84.1% 84.4% 84.5% 84.3%  1 mM acetate buffer 90.5% 91.1% 91.9%91.2% 10 mM acetate buffer 90.9% 90.9% 92.4% 91.4%

TABLE 46 % Total Impurities in the vasopressin formulations afterstorage at 60° C. for 7 days. Sample Buffer 1 2 3 Average  1 mM citratebuffer 3.4% 3.5% 2.5% 3.1% 10 mM citrate buffer 9.5% 9.0% 9.4% 9.3%  1mM acetate buffer 3.3% 2.8% 3.2% 3.1% 10 mM acetate buffer 2.9% 2.6%3.1% 2.9%

The data indicated that the vasopressin assay in the vasopressinformulations with citrate buffer was lower than in the vasopressinformulations with acetate buffer. For example, at 10 mM of eithercitrate or acetate buffer, the average vasopressin assay was 91.4% inacetate buffer, but was 84.3% in citrate buffer. The data also indicatedthat % total impurities in the vasopressin formulations with citratebuffer were higher than in the vasopressin formulations with acetatebuffer. For example, at 10 mM of either citrate or acetate buffer, theaverage % total impurities was 2.9% in acetate buffer, but was 9.3% incitrate buffer.

Further, as the citrate buffer concentration increased, the vasopressinassay further decreased (from an average of 89.9% to 84.3%), and the %total impurities increased (from an average of 3.1% to 9.3%). Thiseffect was not observed in the vasopressin formulations with acetatebuffer, where the average and % total impurities stayed fairly constant.

The results from TABLES 53-54 indicate that stability of the vasopressinformulations was not significantly affected by either inverted orupright storage. The impurities detected included Gly9 (SEQ ID NO.: 2),Glu4 (SEQ ID NO.: 4), D-Asn (SEQ ID NO.: 10), Asp5 (SEQ ID NO.: 3),Acetyl-AVP (SEQ ID NO.: 7), vasopressin dimer, and several unidentifiedimpurities (UI). The unidentified impurities are labeled with a range ofrelative retention times at which the impurities eluted from the column.

The results indicate that the pH remained fairly constant over the15-month period, fluctuating between 3.8 and 3.9 throughout the 15months. The total impurities did not increase over 5.9%, and the % LC ofvasopressin did not decrease below 92%.

FIG. 19 shows a graph depicting the % LC over the 15-month study periodfor the results provided in TABLES 53-54. The starting amounts ofvasopressin were 97.9% LC for lot X, 98.6% LC for lot Y, and 99.3% LCfor lot Z. The results indicate that the % LC of vasopressin decreasedover the 15-month study period, but did not decrease below 92% LC.

The formula for the trend line of lot X was:% LC=98.6−0.4262(month)

The formula for the trend line of lot Y was:% LC=98.47−0.4326(month)

The formula for the trend line of lot Z was:% LC=99.54−0.3906(month)

Example 17 Impurity Measurement for Vasopressin Formulation for Bottleor Intravenous Drip-Bag

Gradient HPLC was used to determine the concentration of vasopressin andassociated impurities in vasopressin formulations similar to thoseoutlined in TABLES 55-63 above. Vasopressin was detected in the eluentusing UV absorbance at a short wavelength. The concentration ofvasopressin in the sample was determined by the external standardmethod, where the peak area of vasopressin in sample injections wascompared to the peak area of a vasopressin reference standard in asolution of known concentration. The concentrations of related peptideimpurities in the sample were also determined using the externalstandard method, using the vasopressin reference standard peak area anda unit relative response factor. An impurities marker solution was usedto determine the relative retention times of identified related peptidesat the time of analysis.

The chromatographic conditions used for the analysis are shown in TABLE64 below:

Diluent A was 0.25% v/v acetic acid, which was prepared by pipetting 2.5mL of glacial acetic acid into a 1 L volumetric flask containing 500 mLof water. The volume was diluted with water and mixed well.

Diluent B was prepared by weighing and transferring about 3 g of sodiumchloride into a 1 L volumetric flask and then adding 2.5 mL of glacialacetic acid. The solution was diluted to volume with water and mixedwell.

Phosphate buffer at pH 3.0 was used for mobile phase A. The buffer wasprepared by weighing approximately 15.6 g of sodium phosphate monobasicmonohydrate into a beaker. 1000 mL of water was added, and mixed well.The pH was adjusted to 3.0 with phosphoric acid. The buffer was filteredthrough a 0.45 μm membrane filter under vacuum, and the volume wasadjusted as necessary.

An acetonitrile:water (50:50) solution was used for mobile phase B. Toprepare mobile phase B, 500 mL of acetonitrile was mixed with 500 mL ofwater.

The stock standard solution was prepared at 20 units/mL of vasopressin.A solution of vasopressin in diluent was prepared at a concentration ofabout 20 units/mL. The stock standard solution was prepared byquantitatively transferring the entire contents of 5 vials of USPVasopressin RS with diluent A to the same 250-mL volumetric flask. Thesolution was diluted to volume with diluent A and mixed well. 10 mLaliquots of the standard solution was transferred into separatepolypropylene tubes. The aliquots were stored at 2-8° C. The stockstandard solution was stable for 6 months from the date of preparationwhen stored in individual polypropylene tubes at 2-8° C.

The working standard solution contained about 0.5 units/mL ofvasopressin. Aliquots of the stock standard solution were allowed towarm to room temperature and then mixed well. 2.5 mL of the stockstandard solution was transferred into a 100 mL volumetric flask anddiluted to volume with Diluent B, and the resultant mixture was denotedas the Working Standard Solution.

The stock standard solution and working standard solution can also beprepared from a single vasopressin vial in the following manner.

One vial of vasopressin with diluent A can be quantitatively transferredto a 50-mL volumetric flask. The solution can be dissolved in anddiluted to volume with diluent A and mixed well, and denoted as thestock standard solution. To prepare the working standard solution, 2.5mL of the stock standard solution was diluted to 100 mL with diluent Band mixed well.

The working standard solution was stable for at least 72 hours whenstored in refrigerator or in autosampler vial at 10° C.

The intermediate standard solution was prepared by pipetting 1 mL of theworking standard solution into a 50 mL volumetric flask. The solutionwas diluted to volume with diluent B and mixed well.

The sensitivity solution (0.1% of 0.4 units/mL vasopressin formulation)was prepared by pipetting 2 mL of the intermediate standard solutioninto a 50 mL volumetric flask. The solution was diluted to the volumewith diluent B and mixed well. The sensitivity solution was stable forat least 72 hours when stored in the refrigerator.

To prepare the impurities marker solution, a 0.05% v/v acetic acidsolution was prepared by pipetting 200 mL of a 0.25% v/v acetic acidsolution into a 1 L volumetric flask. The solution was diluted to thedesired volume with water and mixed well.

To prepare the vasopressin impurity stock solutions, the a solution ofeach impurity as shown below was prepared in a 25 mL volumetric flaskand diluted with 0.05% v/v acetic acid to a concentration suitable forHPLC injection.

-   -   Gly-9 AVP: 0.09 mg/mL    -   Glu-4 AVP: 0.08 mg/mL    -   Asp-5 AVP: 0.1 mg/mL    -   D-Asn AVP: 0.08 mg/mL    -   Dimer AVP: 0.07 mg/mL    -   Acetyl AVP: 0.08 mg/mL

To prepare the MAA/H-IBA (Methacrylic Acid/α-Hydroxy-isobutyric acid)stock solution, a stock solution containing approximately 0.3 mg/mLH-IBA and 0.01 mg/mL in 0.05% v/v acetic acid was made in a 50 mLvolumetric flask.

To prepare the chlorobutanol diluent, about one gram of hydrouschlorobutanol was added to 500 mL of water. Subsequently, 0.25 mL ofacetic acid was added and the solution was stirred to dissolve thechlorobutanol.

To prepare the stock impurity marker solutions, 6.5 mg of vasopressinpowder was added to a 500 mL volumetric flask. To the flask, thefollowing quantities of the above stock solutions were added:

-   -   Gly-9 AVP: 20.0 mL    -   Glu-4 AVP: 20.0 mL    -   Asp-5 AVP: 10.0 mL    -   D-Asn AVP: 10.0 mL    -   Dimer AVP: 10.0 mL    -   Acetyl AVP: 20.0 mL    -   H-IBA/MAA: 30.0 mL

The solutions were diluted to volume with the chlorobutanol diluent. Thesolutions were aliquoted into individual crimp top vials and stored at2-8° C. The solutions, stored at 2-8° C., were suitable for use as longas the chromatographic peaks could be identified based on comparison tothe reference chromatogram.

At time of use the solutions were removed from refrigerated (2-8° C.)storage and allowed to reach room temperature.

The vasopressin stock impurity marker solution was stable for at least120 hours when stored in autosampler vials at room temperature.

The impurity marker solution were prepared by diluting 1 mL of the stockimpurity marker solution to 50 mL with diluent B, and mixed well. Thevasopressin impurity marker solution was stable for at least 72 hourswhen stored in the refrigerator.

To begin the analysis, the HPLC system was allowed to equilibrate for atleast 30 minutes using mobile phase B, followed by time 0 min gradientconditions until a stable baseline was achieved.

Diluent B was injected at the beginning of the run, and had no peaksthat interfered with vasopressin as shown in FIG. 20.

A single injection of the sensitivity solution was performed, whereinthe signal-to-noise ratio of the vasopressin was greater than or equalto ten as shown in FIG. 21.

A single injection of the impurities marker solution was then made. Thelabeled impurities in the reference chromatogram were identified in thechromatogram of the marker solution based on their elution order andapproximate retention times shown in FIG. 22 and FIG. 23. FIG. 23 is azoomed-in chromatograph of FIG. 22 showing the peaks that eluted between16 and 28 minutes. The nomenclature, structure, and approximateretention times for individual identified impurities are detailed inTABLE 3.

A single injection of the working standard solution was made to ensurethat the tailing factor of the vasopressin peak was less than or equalto about 2.0 as shown in FIG. 24.

A total of five replicate injections of the working standard solutionwere made to ensure that the relative standard deviation (% RSD) of thefive replicate vasopressin peak areas was not more than 2.0%.

Following the steps above done to confirm system suitability, a singleinjection of the placebo and sample preparations was made. Thechromatograms were analyzed to determine the vasopressin and impuritypeak areas. The chromatogram for the placebo is depicted in FIG. 25, andthe chromatogram for the sample preparation is shown in FIG. 26. Then,the working standard solution was injected after 1 to 10 sampleinjections, and the average of the bracketing standard peak areas wereused in the calculations for vasopressin and impurity amounts.Additional injections of the impurities marker solution could be made tohelp track any changes in retention time for long chromatographicsequences.

The relative standard deviation (% RSD) of vasopressin peak areas forthe six injections of working standard solution was calculated byincluding the initial five injections from the system suitability stepsabove and each of the subsequent interspersed working standard solutioninjections. The calculations were done to ensure that each of the % RSDwere not more than 2.0%.

The retention time of the major peak in the chromatogram of the samplepreparation corresponded to that of the vasopressin peak in the workingstandard solution injection that preceded the sample preparationinjection.

To calculate the vasopressin units/mL, the following formula was used:

${{Vasopressin}\mspace{14mu}{units}\text{/}{mL}} = {\frac{R_{U}}{R_{S}} \times {Conc}\mspace{14mu}{STD}}$

where:

-   -   R_(U)=Vasopressin peak area response of Sample preparation.    -   R_(S)=average vasopressin peak area response of bracketing        standards.    -   Conc STD=concentration of the vasopressin standard in units/mL

To identify the impurities, the % Impurity and identity for identifiedimpurities (TABLE 3) that are were greater than or equal to 0.10% werereported. Impurities were truncated to 3 decimal places and then roundedto 2 decimal places, unless otherwise specified. The following formulawas used:

${\%\mspace{14mu}{impurity}} = {\frac{R_{1}}{R_{s}} \times \frac{{Conc}\mspace{14mu}{STD}}{L\; C} \times 100\%}$

-   -   where R₁=Peak area response for the impurity; LC=label content        of vasopressin (units/mL).

The formulations used for the vasopressin and impurity studies aresummarized in TABLE 65 below and correspond to several of theformulations detailed above in TABLES 55-63.
